The group of succulents known as Stapelias originate in southern and southwest Africa. They belong to the milkweed family, Asclepiadaceae.
Stapelias are very decorative plants. Each thick, succulenthas four ribs with toothed edges. The branch out at the base and form dense clumps; the spreading habit of these plants make them suitable for growing in wide, shallow containers.
The star-shapedare most unusual and attractive, and in some varieties are sweetly scented. However, the flowers of Stapelia variegata have an unpleasant, although not overpowering, odour. The odour is similar to that of rotting meat, and attracts the blowflies which the flowers.
The varieties grown as house plants can vary in height from 10-23cm (4– 9in), with large flowers that can be 8-38cm (3-14in) in diameter. All varieties grow quickly in the summer; there is no growth in winter.
The most commonly grown variety is Stapelia variegata. It grows to a height of 10cm (4in) and is easy to bring into bloom. The flowers, which are pale yellow and patterned with brownish-purple markings, are about 8cm (3in) across. They appear in August.
Another popular variety, and the easiest to grow, is S. hirsuta. Both the stems and the flower petals are covered with soft hairs. The flowers are yellow with brown markings, and the hairs reddish-brown.
S. gigantea has the largest flowers of all varieties —they can be 36cm (14in) in diameter. The velvety stems are 15– 20cm (6-8in) in height.
